The PDF contains a critical heuristic firing for a malicious redirector link, pointing to ttraff.ru. The document body, though heavily obfuscated, contains this URL and numerous other links, many hosted on cdn.shopify.com, suggesting a link farm or SEO poisoning attempt. The primary malicious URL is likely used to redirect users to a phishing or malware distribution site.

Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
